摘要: 植物间的相互作用是生态学领域关注的重要方向之一,其对高效利用养分资源、提高生产力以及构建植物群落均具有重要意义。丛枝菌根真菌是重要的植物互惠共生微生物,其菌丝可以将邻近植物的根部连接起来,形成共同的菌丝网络(CMNs),这些网络对转移养分、水分以及调节植物群落具有重要作用。近期的研究表明,CMNs可以充当植物之间传递病害和蚜虫诱导信号的通道,并激活邻近植物(未受感染)的化学防御。本文围绕最新的CMNs在植物相互作用中的研究成果,总结了影响CMNs规模及其功能活性的主要因素,阐述了CMNs在植物间养分、水分转移及再分配中的作用,并对CMNs在地下化学信号交流、幼苗建植及群落构建的作用机制进行了系统回顾,最后展望了该研究领域中存在的问题,旨在为进一步理解CMNs在植物互作中的生态学功能提供参考。

Abstract: Plant-plant interactions is one of the key field in ecology, which is important for the efficient nutrient utilization, productivity improvement, and plant community assembly. Arbuscular mycorrhizal fungi are important plant mutualistic microorganisms that connect plant roots to form common mycelial networks (CMNs), which play major roles in transferring nutrients and water and regu-lating plant community dynamics. Recent studies demonstrated that these CMNs could act as conduits for transmitting disease and aphid-induced signals among plants, and activating chemical defence in uninfested neighboring plants. In this review, we introduced recent research advances on the contribution of CMNs on plant interaction, the main factors that influences the functions of CMNs, and the role of CMNs transfer and redistribute nutrients and water among plant. In addition, the mechanism underlying underground chemical signal communication, seedling establishment and plants community assembly were summarized. Finally, we proposed challenges facing CMNs in plant-plant interactions and the practical problems. It would provide reference for further understanding the ecological functions of CMNs in plant-plant interactions.
